Take the stress out of teaching the Arctic Tundra case study for OCR A Level Geography (H481) Earth’s Life Support Systems with this complete three-lesson teaching bundle. Designed to build understanding progressively, Lesson 1 explores how Arctic climate, permafrost, relief and other physical controls create distinctive water and carbon cycles; Lesson 2 investigates seasonal change, including freeze–thaw, snowmelt, active-layer changes and seasonal variations in water and carbon stores and flows; and Lesson 3 examines the impact of oil and gas development on Alaska’s North Slope, including altered drainage, permafrost degradation, vegetation disturbance, carbon release, management strategies and positive feedback. The lessons feature clear geographical diagrams, engaging retrieval and enquiry activities, causal-chain thinking, synoptic links between the water and carbon cycles, evaluation tasks and OCR-style exam practice, including a 10-mark question. Accompanying student worksheets help students build a detailed, revision-ready case study while developing the explanation, application and judgement skills needed for the exam. Ideal for delivering the Arctic tundra case study as a coherent mini-unit or for revising Earth’s Life Support Systems before assessments.
